Ex-colleague asked for help in regards to an old project we were working at my old job

Him:"We're experiencing an internal server error. What do we do?"
Me:"Restart tomcat, dude"
Him:"How?"

Then I explained how by finding tomcat in ps -ef in a Redhat server, because he's a Linux noob and needed a lesson in how services works. Proceeded to explain how to restart tomcat with an online guide available.

Him:"Couldn't find tomcat in any of the servers"
Me:"Are you sure? Send me screenshots"
Him: sent screenshots
Me:"it's there. Look carefully."
Him: finds it and proceeded to restart tomcat.
Him: "Can't restart. Some catalina.sh is stopping it."
Me:"Figure it out. You can do it".

Half a day passed...

Him:"I give up. If I restart the server, will tomcat also restart?"
Me:"Up to you man. It will work but it's bad practice."

He restarted the server vand now everything is honky dory. I feel sorry for him though.
